Gas Costs
Natural gas utilities buy gas for their customers in a competitive wholesale market. Indiana law allows utilities to adjust rates every three months to recover changes in those costs, which can go up or down. These costs comprise a significant portion of a residential bill and are recovered through the Gas Cost Adjustment (GCA) process.
- Utilities may recover wholesale gas costs on a dollar-for-dollar basis but may not profit on them.
- Before adjusting rates to reflect the costs, a utility must demonstrate that it has shopped prudently in the competitive market.
- Each GCA filing requires OUCC review and IURC approval.
The utility's most recently approved request (Cause No. 37418 GCA-163) will affect bills for November 2024, December 2024, and January 2025.
Base Rates
Base rates cover a utility's operational, maintenance, and capital costs. Investor-owned utilities are allowed to earn a return on base rates.
The IURC approved Indiana Natural Gas Corporation's base rates in 2014.
